HI,
I have random hard reboots since november on my server (Asrock J4105-ITX with a WD 14TB HDD and a Samsung 850 pro 512GB SDD) . I couldn't find the cause until yesterday:
When I enable SMART monitoring in OMV UI the system randomly hard reboot every few hours/days without anything in logs.
If then I disable SMART monitoring in OMV UI the problem (random reboots) stays until I completely power-off/power-on the server.
I suspect this commit trigger a bug with the samsung SDD 850 pro firmware and the bug stays until a complete power-off.
For now I disabled SMART monitoring and my system is stable again.
What can I do to help fix the problem?
